The record
The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.1.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view, create, update, clone, and delete notification flow event automation workflows that should be restricted to administrators.
